The injection molding unit of general injection molding machine provides two functions in fact in normal operation period; Be injection moulding and extruding.When feed screw travels forward (do not have rotate) when forcing plastic melt to enter into mould along straight line, carry out the injection moulding function.When feed screw is rotated when plastifying the other material of injection next time, finish squeeze function.When feed screw was rotated in the squeeze function process, plastic melt was forced to gradually the end by screw rod, produces pressure or force screw rod to move to its pre-injection moulding position backward when melt gathers.
Injection moulding and squeeze function all need the relevant drive unit in the injection molding unit.In the hydraulic machinery of prior art, the injection moulding FM is generally finished by hydraulic cylinder, and the rotation of the feed screw of extruding operation is normally finished by hydraulic motor.Recently, the motor that combines with mechanical system has been used as the direct driving force source in the injection molding unit.Some electrical system of the prior art is used independent motor to each function; Promptly be used to rotate motor of feed screw and combine rotational motion is converted to required straight-line one second motor of injection moulding with a mechanism of for example ball screw and so on.Other " hybrid " of the prior art machinery uses a motor to rotate feed screw, and all the other functions that should machinery are hydraulically powered, provide power by a motor that drives one or more hydraulic pumps.
" although hybrid " machinery has made up electric (controlling screw rod better rotates) and some mechanical advantage of hydraulic pressure (reduction totle drilling cost), but still exist room for improvement.Especially, because in the motor of rotating screw bolt, have superfluous capacity, so there is the possibility that a more economic system is provided.This motor only uses at thermoplastic material and is extruded in (plasticizing) that part of cyclic process for injection.Because motor and relevant variable speed drives thereof have relative higher cost, be desirable with the utilization of this motor maximization.In addition, for the injection molding machine that has the variable-speed motor that to buy at present, this motor or be exclusively used in specific axle (as machine-electric system) perhaps is applied to titer volt circuit capacity surplus, therefore by variable-speed motor with drive and do not obtain economic control.
Of the present invention open
Therefore, the object of the present invention is to provide a kind of simple in structure and can make single variable-speed motor be used for providing the drive unit of energy effectively to machinery and the combination of hydraulic machine parts.
In brief, the present invention relates to a drive unit, it preferably is a brushless direct current and a variable-speed motor that has traditional power transmission component that this drive unit has, in order to alternately to provide: (a) rotation of the feed screw in the injection molding unit of an injection molding machine, perhaps the running of (b) hydraulic pump group provides power with the hydraulic system of giving machine.This drive unit also has at first one-way clutch (clutch) between motor and the feed screw and second one-way clutch between motor and hydraulic pump group.
In the running of most of machine function, this drive motor rotates to rotate the power shaft of pump group along (clockwise) direction forward, gives operation factor, for example clamping and injection moulding in the various kinematic axis thus.Come the hydraulic power of self-pumping group also to can be used to the energy supply of hydraulic pressure accumulator, motor be not used for interim of driving pump provide hydraulic pressure can deposit.Say that more specifically forward in the rotating process, (a) first one-way clutch is engaged, and rotates the axle of pump group at drive motor; And (b) second one-way clutch slip.

Implement optimal mode of the present invention
To the present invention be described in conjunction with a typical injection molding machine 1 with clamping system 2 and injection molding unit 10.As shown in figs. 1 and 4, injection molding unit 10 is connected to horizontal supporting bar 4 carryings of the base portion 8 of injection molding machine 1.Injection molding unit 10 is suitable for moving along being used to locate purpose cramp bar 4, for example be connected fixation clip 6 on mould (not shown) link to each other.
The chief component of injection molding unit 10 comprises a tube 12 (Fig. 4) that contains feed screw 14, and feed screw 14 makes the thermoplastic material plasticising that enters into tube 12 from funnel 16 by housing 15.The operational function that comprises the injection molding machine 1 of injection molding unit 10 is started by driven unit 18.The driven unit 18 of injection molding unit 10 comprises the shaft coupling 22 of a motor 20, pump driving, shaft coupling 24, hydraulic pump group 26 and the support housing 28 that extruder drives, referring to Fig. 2 and 4.As in following paragraph, will carry out more detailed as described in, this driven unit 18 will rotate feed screw 14 making material plasticising in squeeze function, and produce the required hydraulic power of other mechanical function.
Specifically referring to Fig. 5, driven unit 18 has the pump that motor 20 is connected on the hydraulic pump group 26 and drives shaft coupling 22.The axle that is installed in motor 20 on 38 is an one-way clutch 42 and two roller bearing components 44, and they support and engage the shaft coupling sleeve 40 on the axle 34 that directly is connected pump group 26 jointly.As following will carry out more comprehensive as described in, motor 20 can rotate along either direction, unidirectional clutch 42 only can rotate pulley 40 along direction.In disclosure text, each parts that is described to " one-way clutch " preferably for be used for engaging an one-directional rotation, have around the mechanical cam type clutch of a slewing circle column piece of body; When this cylinder rotates in opposite direction, in fact there is not any resistance from clutch.Morse Industrial, Emerson PowerTransmission company are the well-known suppliers of the type clutch.
One motor mounting plate 51 directly is connected on the support housing 36 and is configured to along guide post 30 and moves with support housing 28.As shown in the figure, motor 20 is located immediately at the top of installing plate 51.
The running of driven unit 18 is now described.In order to start the function of extruder, drive motor 20 so that its rotate in the counterclockwise direction.The rotation of motor reel 38 causes one-way clutch 66 to engage, thereby drive pulley 64 is also followed drive pulley 72 by driving-belt 70.The rotation of pulley 72 passes to feed screw 14 with identical rotation.When feed screw 14 rotates, plastify by housing 15 chargings and in tube 12 for the material that comes from funnel 16.The rotation of feed screw 14 makes material advance towards the nozzle (discharging) of tube 12 end, when the material of filling begins to gather, increases at the pressure of the melt of screw rod 14 ends.When the pressure of plastic melt reached certain degree, it began to force feed screw 14 to move backward, makes whole driven unit 18 move to the rear portion of injection molding unit 10 thus.Specifically, the motion backward of feed screw 14 applies a power for housing 36, causes the housing 36 that is carrying motor 20, pump group 26 and relevant drive part similarly to move backward.
The motion backward of feed screw 14 can be controlled (referring to Fig. 1) by the hydraulic cylinder 46 of the either side that is connected housing 36.Can the slow down motion backward (but not influencing rotation) of feed screw 14 of the suitable valve control of the fluid in the hydraulic cylinder 46 increases the support pressure of plastic melt thus.In addition, hydraulic cylinder 46 also can be used in the mode that increases the speed that feed screw retreats power is applied on the housing 36, reduces the support pressure of melt thus.
When motor 20 rotated in squeeze function in the counterclockwise direction, unidirectional clutch 42 slided on axle 38, did not therefore have rotatory force to be delivered on the pump shaft 34.Fill the required plastic melt of cavity body of mould that is installed on the fixation clip 6 when accumulating in feed screw 14 anterior when being enough to fill up, just finished squeeze function.
In case after having finished squeeze function, motor 20 promptly reverses, it rotates along clockwise direction thus, the result, and unidirectional clutch 42 is bonded on the axle 38, thus the axle 34 of rotating joint sleeve 40 and hydraulic pump group 26.The hydraulic power that pump group 26 is produced is used for moving machine function and/or to hydraulic accumulator 48 energy supplies, this is determined by the operation order of injection molding machine 1.For example, in order to fill up capable injection moulding function, hydraulic energy guides to hydraulic cylinder 46 by means of suitable valve control (not shown); The hydraulic cylinder running is to be transmitted to feed screw 14 by applying power for housing 36 with rectilinear motion.
It is outer and enter into cavity body of mould that the travelling forward of feed screw 14 causes the plastic melt of the end that accumulates in tube to be discharged from tube.In injection moulding process, one brake motor 50 is delivered on the driving-belt 70 with will be enough big power by energy supply, prevents that feed screw 14 from rotating (torque that the power generation that is positioned at the plastic melt on the feed screw 14 of motion is tending towards rotating feed screw 14) along clockwise direction when travelling forward with the injection moulding plastic melt at feed screw 14.After finishing the injection moulding function, hydraulic cylinder 46 is used for keeping pressure (" compress and keep ") on the plastic melt to guarantee suitably to form parts.
When compressing and keep initial at interval, motor 20 counter-rotatings are with beginning as another above-mentioned squeeze function.Accumulator 48 provides the required hydraulic energy of operation that keeps hydraulic cylinder 46 when motor 20 rotates feed screw 14.Similarly, finish compress and keep after, accumulator 48 will provide hydraulic energy to open mould.According to the duration of extruding running, the required hydraulic energy of closed clamp clamping system can provide by accumulator 48 and/or as the required pump group 26 of the part of injection molding machine 1 when being used for moving spraying system and/or preparing injection moulding.
